An interview with Nobel Laureate Sydney Brenner:
I think there was a time, and I’m trying to trace the history when the rights to publish, the copyright, was owned jointly by the authors and the journal. Somehow that’s why the journals insist they will not publish your paper unless you sign that copyright over. It is never stated in the invitation, but that’s what you sell in order to publish. And everybody works for these journals for nothing. There’s no compensation. There’s nothing. They get everything free. They just have to employ a lot of failed scientists, editors who are just like the people at Homeland Security, little power grabbers in their own sphere.
If you send a PDF of your own paper to a friend, then you are committing an infringement. Of course they can’t police it, and many of my colleagues just slap all their papers online. I think you’re only allowed to make a few copies for your own purposes. It seems to me to be absolutely criminal. When I write for these papers, I don’t give them the copyright. I keep it myself. That’s another point of publishing, don’t sign any copyright agreement. That’s my advice. I think it’s now become such a giant operation. I think it is impossible to try to get control over it back again.
